Close scrutiny of Goodenia (Goodeniaceae) and allied genera in the ‘Core Goodeniaceae’ over recent years has clarified our understanding of this captivating group. While expanded sampling, sequencing of multiple regions, and a genome skimming reinforced backbone clearly supported Goodenias.l. as monophyletic and distinct from Scaevola and Coopernookia, there appears to be no synapomorphic characters that uniquely characterise this morphologically diverse clade. Within Goodenias.l., there is strong support from nuclear, chloroplast and mitochondrial data for three major clades (Goodenia Clades A, B and C) and various subclades, which lead to earlier suggestions for the possible recognition of these as distinct genera. Through ongoing work, it has become evident that this is impractical, as conflict remains within the most recently diverged Clade C, likely due to recent radiation and incomplete lineage sorting. In light of this, it is proposed that a combination of morphological characters is used to circumscribe an expanded Goodenia that now includes Velleia, Verreauxia, Selliera and Pentaptilon, and an updated infrageneric classification is proposed to accommodate monophyletic subclades. A total of twenty-five new combinations, three reinstatements, and seven new names are published herein including Goodenia subg. Monochila sect. Monochila subsect. Infracta K.A.Sheph. subsect. nov. Also, a type is designated for Goodenia subg. Porphyranthus sect. Ebracteolatae (K.Krause) K.A.Sheph. comb. et stat. nov., and lectotypes or secondstep lectotypes are designated for a further three names.

最后一章:牙粉刺(Goodeniaceae)的重新划界,包括四个同属属,具有更新的基础遗传学分类。

近年来,对“核心Goodeniaceae”中的Goodenia(Goodeniaceae)和相关属进行了仔细的研究,这使我们对这个迷人的群体的理解更加清晰。在扩大采样范围的同时,对多个区域进行测序,以及撇除基因组的增强主链显然支持了Goodenias.l。由于是单系的,不同于Scaevola和Coopernookia,似乎没有突触性特征可以独特地表征这种形态多样的进化枝。在Goodenias.l。内部,三个主要进化枝(Goodenia进化枝A,B和C)和各个子进化枝的核,叶绿体和线粒体数据均提供了有力的支持,这导致了较早提出的将它们识别为不同属的建议。通过正在进行的工作,很明显这是不切实际的,因为冲突仍然存在于最近分裂的Clade C,可能是由于最近的辐射和血统分类不完整所致。鉴于此,建议使用形态学特征的组合来限制现在包括Velleia,Verreauxia,Selliera和Pentaptilon的扩展的Goodenia,并提出更新的基础类目以适应单系子系。本文总共发布了25种新组合,3种恢复功能和7种新名称,包括Goodenia subg。Monochila教派。Monochila亚科。Infracta KASheph。子领域。十一月 另外,为Goodenia subg指定了一种类型。紫菜属。br科(K.Krause)KASheph。梳。等统计。nov。和lectotypes或secondstep lectotypes被指定为另外三个名称。有人建议使用形态学特征的组合来界定一个扩展的古德尼亚,该古德尼亚现在包括Velleia,Verreauxia,Selliera和Pentaptilon,并且提出了一种更新的基础遗传分类来适应单系子代。本文总共发布了25种新组合,3种恢复功能和7种新名称,包括Goodenia subg。Monochila派。Monochila亚科。Infracta KASheph。子领域。十一月 另外,为Goodenia subg指定了一种类型。紫菜属。br科(K.Krause)KASheph。梳。等统计。nov。和lectotypes或secondstep lectotypes被指定为另外三个名称。有人建议使用形态学特征的组合来界定一个扩展的古德尼亚,该古德尼亚现在包括Velleia,Verreauxia,Selliera和Pentaptilon,并且提出了一种更新的基础遗传分类来适应单系子代。本文总共发布了25种新组合,3种恢复功能和7种新名称,包括Goodenia subg。Monochila教派。Monochila亚科。Infracta KASheph。子领域。十一月 另外,为Goodenia subg指定了一种类型。紫菜属。br科(K.Krause)KASheph。梳。等统计。nov。和lectotypes或secondstep lectotypes被指定为另外三个名称。并提出了更新的亚基分类来适应单系子代。本文总共发布了25种新组合,3种恢复功能和7种新名称,包括Goodenia subg。Monochila教派。Monochila亚科。Infracta KASheph。子领域。十一月 另外,为Goodenia subg指定了一种类型。紫菜属。br科(K.Krause)KASheph。梳。等统计。nov。和lectotypes或secondstep lectotypes被指定为另外三个名称。并提出了更新的亚基分类来适应单系子代。本文总共发布了25种新组合,3种恢复功能和7种新名称,包括Goodenia subg。Monochila教派。Monochila亚科。Infracta KASheph。子领域。十一月 另外,为Goodenia subg指定了一种类型。紫菜属。br科(K.Krause)KASheph。梳。等统计。nov。和lectotypes或secondstep lectotypes被指定为另外三个名称。
